Remote Monitoring System for Unmanned Vehicle Signal Based on Vector Sensor

Due to the influence of signal transmission distance, the traditional remote detection system for driverless vehicles has the problem that the clarity of the monitoring signal is reduced under the attenuation of circuit coupling rate, and the overall monitoring effect of the signal can not meet the application requirements of the actual detection system. In this design system, vector sensors are used to calculate the system variables, modulus and quantitative data, and a remote signal monitoring system for driverless vehicles based on vector sensors is proposed. Firstly, the overall framework design of the system based on vector sensor is completed; secondly, according to the design framework, the interactive hardware unit of unmanned vehicle monitoring signal is established, and the vector conversion calculation platform of monitoring signal data is constituted by different vector sensors; finally, through the vector quantization software adaptation of the hardware platform, the unification of hardware and software monitoring signal is completed, the signal transmission strength is improved, and the efficiency is improved In order to meet the requirements of remote signal monitoring for driverless vehicles, the design of the proposed system is completed. By comparing the experimental data, it shows that the remote monitoring system of driverless vehicle signal based on vector sensor can stably monitor the vehicle status in the range of 50km ~ 100km, and the real-time and continuity of vehicle status data monitoring is obviously better than the traditional detection system.
